From the title, I thought this was a factorization of the RSA-2048 integer (i.e., the one you get the prize for factoring). So I quickly skimmed to the results section to see what the factors where.
It's not. It's a factorization of the product of two 1024-bit numbers that are known to differ only in two bits (and the bit positions they differ may also be an input to the algorithm, not clear on that). The only relevance to RSA-2048 is that it's not technically a lie that they factored a 2048-bit integer.
